Plan the big FOVcoronal slices on the axial image position the block across the liver as shown. These are fast single shot localisers with under 25s acqusition time which are excellent for localising abdominal structures. Suggested protocols, parameters and planningĪ three plane TrueFISP localiser must be taken initially to localise and plan the sequences. Give a pillow under the head and cushions under the legs for extra comfortĬentre the laser beam localiser over xiphoid process of sternum Securely tighten the body coil using straps to prevent respiratory artefacts Position the patient over the spine coil and place the body coil over the upper abdomen (nipple down to iliac crest) Position the patient in supine position with head pointing towards the magnet (head first supine) Offer headphones for communicating with the patient and ear protectionĮxplain the procedure to the patient and answer questions Patients should fast for 4 -6 hours before the exam (nothing to eat or drink) by staff member or relative with proper safety screeningĪn intravenous line must be placed with extension tubing extending out of the magnetic bore Instruct the patient to hold their breath for the breath hold scans and breathe gently for the gated scans (its advisable to coach the patient two to three times before starting the scan)Ĭlaustrophobic patients may be accompanied into the scanner room e.g. Pregnancy (risk vs benefit ratio to be assessed)Ī satisfactory written consent form must be taken from the patient before entering the scanner roomĪsk the patient to remove all metal object including keys, coins, wallet, any cards with magnetic strips, jewellery, hearing aid and hairpinsĪsk the patient to undress and change into a hospital gown Intracranial aneurysm clips (unless made of titanium) cardiac pacemaker, insulin pump biostimulator, neurostimulator, cochlear implant, and hearing aids)
The pancreas is a long, flattened, irregularly shaped, fragile accessory digestive gland, lying behind the stomach and between the c loop of duodenum and the spleen.Īny electrically, magnetically or mechanically activated implant (e.g. Secretin-stimulated MRCP is frequently used to examine the pancreatic ductal anatomy in order to detect any pancreatic ductal pathologies. Secretin relaxes the sphincter of Oddi that opens the pancreatic duct orifices. Secretin helps to increase the bicarbonate and pancreatic fluid secretion by the exocrine cells.
Secretin is a hormone ( 27-amino acid polypeptide) produced by ductal mucosa in response to acid and food in the duodenum. > Screening for patients at high risk for pancreatic adenocarcinoma > Assessment of decreased exocrine reserve in chronic pancreatitis > Evaluation of leakage of pancreatic juice associated with acute pancreatitis Assessment of segmental stenosis of pancreatic duct in chronic pancreatitis
